PROCEDURE:
All of the following steps must be performed with the utmost
care, precision and attention
• Use the "roller" extractor suitable (among the three
supplied Ø2.5 - Ø3.5 - Ø4) to remove the terminal part of
the electrode of the spark plug (fig. 1).
Reference codes: 03700L-1, 03700L-2, 03700L-3
Tools required: Wrench 3/8 "
•
If necessary, in the case part of the central electrode
should remain, take the conical driving sheath (among the
two provided with inner hole Ø2.7 - Ø3.6) and put it on the
remained part of electrode (fig. 3).
Reference codes: 03700L-4, 03700L-5
• Use the extension + bit suitable (among the two supplied
with tip Ø2.7 or Ø3.6) to remove the portion of the
electrode remained (fig. 3).
Reference codes: 03700L-6, 03700L-7
Tools required: Electric/pneumatic drill
• Make the pilot hole for the extraction of the glow plug (fig.
4) using the long cylindrical spiral bit Ø5,5 (M10) or Ø4,5 (M9,
M8) included in the kit.
Reference codes: 03700L-8, 03702L-1
Tools required: Electric/pneumatic drill
•
Use the extension + bit with 2 diameters and begin the
drilling operation, taking care to drill in small sections (1 to
2 mm) and blow to remove the metal shavings, until the bit
reaches the stop shoulder and removes completely the
threaded part of the glow plug.
In this way you have removed the upper part of the glow
plug (fig. 5).

For the drilling depth and the choice of the bit with 2
diameters (for the next step) follow the diagram below.
To have a limit point of reference for the drilling depth,
we recommend the use of adhesive tape.
